Representation of Racially Minoritized Patients on Dermatology Private Practice Websites.

Images on the homepages of private practice dermatology websites often do not reflect the racial diversity of the metropolitan area in which each practice is located. A Google Maps scraper (Apify) was used to identify websites for private practices in 27 United States metropolitan areas selected from the 2020 U.S. Census list of 100 largest areas where non-white individuals makeup more than 50% of the population. Homepages from the top ten websites listed by the search engine were analyzed for images, use of non-English language, and mention of "Skin of Color" or "Ethnic Skin." One hundred seventeen websites were included. Two mentioned "Skin of Color" or "Ethnic Skin"; seven mentioned a non-English language. A significantly lower percentage of non-white-presenting patients (p < 0.001) and providers (p < 0.001) were pictured on the selected dermatology websites than reported in the Census. These findings suggest that the images on the homepages of private practice dermatology websites were not reflective of the racial diversity of the metropolitan area in which each practice is located. Private practice dermatologists should be mindful of how their services are represented online, as it may dissuade potential minoritized patients from seeking dermatologic care.

Access to Urogynecologic Care in Federally Qualified Health Centers: A Mystery Caller Study.

IMPORTANCE: Federally Qualified Health Centers (FQHCs) play an important role in providing care to underserved populations. However, little is known about the availability of urogynecology services at FQHCs. OBJECTIVES: This study aimed to assess the availability of appointments for urogynecology care and to determine the prevalence of FQHCs offering urogynecologic services. STUDY DESIGN: A total of 362 FQHCs across the United States were randomly selected from the Health Resources and Services Administration website, based on specific inclusion criteria. Researchers called the FQHCs and requested the earliest available appointment for pelvic organ prolapse. The availability of urogynecologic services such as pessary fittings, pelvic floor physical therapy, and urodynamic studies was also inquired. RESULTS: A total of 362 FQHCs located in 46 states and the District of Columbia were called. On average, the 362 FQHCs had been established for 19.9 (SD ±15) years, were located in urban areas, and served a median county population of 24,573. Of the 220 FQHCs successfully contacted, 81% (180/220) reported that they could provide care for a patient with pelvic organ prolapse at an appointment 29.1 business days (SD ±30 days) from the date of the call, on average. However, only a small percentage of these FQHCs offered in-office pessary fittings (11%), complex multichannel urodynamics testing (8.6%), or pelvic floor physical therapy (5%). CONCLUSION: The availability of treatments for pelvic floor disorders at FQHCs is limited. These findings highlight a potential disparity in access to urogynecology services for individuals with public insurance.

Comparison of the Skindex-Teen and the Skindex-29 quality of life survey instruments in a predominantly American Indian adolescent population.

BACKGROUND/OBJECTIVES: The Skindex-29 and Skindex-Teen assess dermatology-related quality of life among adults and adolescents, respectively. This study directly compared the same adolescents' responses to the Skindex-29 relative to Skindex-Teen in a predominantly American Indian and/or Alaska Native population. This population is underrepresented in medical research. Although skin-related quality-of-life issues are widespread, American Indian and/or Alaska Native adolescents are not well-represented in related studies. METHODS: Data were collected in-person by self-report survey at two regional powwows in Denver, Colorado in 2021 and 2022. Respondents completed the full Skindex-29 and Skindex-Teen (40 unique items total). RESULTS: Eighty-six adolescents, 12-17 years old, completed the survey. The majority (70.9%, 61/86) of respondents self-identified as American Indian and/or Alaska Native. Analyses were conducted with all respondent survey data. Nearly two-thirds (64.0%, 55/86) of our respondents had a Skindex-29 score that revealed their quality of life was impaired at least mildly by skin disease. The Skindex-29 and Skindex-Teen demonstrated good reliability; there was substantial concordance between responses to the two measures (r values ranged from 0.88 to 0.97 for similar subscales). Compared to younger adolescents (aged 12-14), older adolescents (aged 15-17) reported worse dermatology-related quality of life and emotional toll based on higher Skindex-29 total, Skindex-Teen total, Skindex-29 Emotional subscale, and Skindex-Teen Psychosocial Functioning subscale scores. CONCLUSIONS: American Indian and/or Alaska Native adolescents suffer from skin-related quality-of-life issues. The Skindex-Teen and Skindex-29 generated similar information regarding quality of life in young patients with skin disease. While the Skindex-Teen may be slightly more relevant to adolescents, these surveys were highly concordant. Both the Skindex-Teen and Skindex-29 exhibited frequent "never" responses to questions about impact of skin conditions on relationships with others and tendencies to stay home. Thus, careful attention should be paid to such questions to ensure their relevance to adolescents.

A solitary scalp mass as the presenting feature of clear cell sarcoma of the kidney in a pediatric patient.

Clear cell sarcoma of the kidney is a rare renal malignancy, accounting for 2%-4% of all pediatric renal tumors. In this case report, we describe a 9-year-old boy with an asymptomatic, solitary mass on the scalp, ultimately found to be metastatic clear cell sarcoma of the kidney. This report reviews indications for imaging scalp masses to facilitate making an accurate diagnosis and treatment planning.

Publication Trends of Qualitative Research in Dermatology: A Scoping Review.

Importance: Qualitative studies serve as a tool for dermatologists and researchers in dermatology to engage with and understand perspectives of populations with different cultures and backgrounds. Objective: To assess (1) current approaches to qualitative dermatologic research and (2) the publication trends of these studies with the aim to inform researchers regarding qualitative research and its significance and applicability in the field of dermatology. Evidence Review: A scoping review was conducted in which PubMed and CINAHL Plus were searched using dermatology AND qualitative, dermatology, and 7 qualitative methods terms. Studies were selected for inclusion using 3 levels of screening. Level 1 excluded articles published in a language other than English. Level 2 excluded articles of studies involving mixed methods, quantitative methods, systematic review, and meta-analysis. Level 3 excluded articles that were not specific to general dermatology, medical dermatology, pediatric dermatology, dermatologic surgery, dermatopathology, or education and training associated with dermatology. Finally, all duplicates were removed. The searches were conducted from July 23 to 28, 2022. All articles obtained from PubMed and CINAHL Plus searches were recorded in REDCap. Findings: A total of 1398 articles were reviewed, and of these, 249 (17.8%) were qualitative dermatology studies. Common qualitative methods included content analysis (58 [23.3%]) and grounded theory/constant comparison (35 [14.1%]). Individual interviews were the most common data collection method (198 [79.5%]), and patients (174 [69.9%]) were the most common participant type. Patient experience (137 [55.0%]) was the most common investigated topic. Overall, 131 qualitative studies (52.6%) in dermatology were published in dermatology journals, and 120 qualitative studies (48.2%) in dermatology were published between 2020 and 2022. Conclusions and Relevance: Qualitative research in dermatology is becoming more prevalent. There is value in qualitative research, and we encourage researchers in dermatology to incorporate qualitative methods in their studies.

Dermatology Access and Needs of American Indian and Alaska Native People.

OBJECTIVES: To describe skin disease prevalence, access to dermatologic care, and teledermatology interest among American Indians and Alaska Natives. METHODS: Data were collected via self-report surveys administered in person at two community powwows in Denver, Colorado in 2021 and 2022. RESULTS: Most American Indian and/or Alaska Native respondents (94.5%, n=225) reported at least one skin disease. The top three active skin diseases among adolescents were acne, scarring, and eczema. The top three among adults were dry skin, hair loss, and acne. Only 20.9% (n=47) of respondents with skin disease had seen a dermatologist. Approximately one-third of respondents (34.0%, n=81) were open to engaging with teledermatology in their home; 43.3% (n=103) were open to engaging with teledermatology in their local clinic; 42.0% (n=100) were not interested in engaging teledermatology from their home or in their local clinic. CONCLUSIONS: Skin disease is prevalent and access to dermatologic care is poor among American Indian and Alaska Native people.

Molecular characterization of putative neuropeptide, amine, diffusible gas and small molecule transmitter biosynthetic enzymes in the eyestalk ganglia of the American lobster, Homarus americanus.

The American lobster, Homarus americanus, is a model for investigating the neuromodulatory control of physiology and behavior. Prior studies have shown that multiple classes of chemicals serve as locally released/circulating neuromodulators/neurotransmitters in this species. Interestingly, while many neuroactive compounds are known from Homarus, little work has focused on identifying/characterizing the enzymes responsible for their biosynthesis, despite the fact that these enzymes are key components for regulating neuromodulation/neurotransmission. Here, an eyestalk ganglia-specific transcriptome was mined for transcripts encoding enzymes involved in neuropeptide, amine, diffusible gas and small molecule transmitter biosynthesis. Using known Drosophila melanogaster proteins as templates, transcripts encoding putative Homarus homologs of peptide precursor processing (signal peptide peptidase, prohormone processing protease and carboxypeptidase) and immature peptide modifying (glutaminyl cyclase, tyrosylprotein sulfotransferase, protein disulfide isomerase, peptidylglycine-α-hydroxylating monooxygenase and peptidyl-α-hydroxyglycine-α-amidating lyase) enzymes were identified in the eyestalk assembly. Similarly, transcripts encoding full complements of the enzymes responsible for dopamine [tryptophan-phenylalanine hydroxylase (TPH), tyrosine hydroxylase and DOPA decarboxylase (DDC)], octopamine (TPH, tyrosine decarboxylase and tyramine ß-hydroxylase), serotonin (TPH or tryptophan hydroxylase and DDC) and histamine (histidine decarboxylase) biosynthesis were identified from the eyestalk ganglia, as were those responsible for the generation of the gases nitric oxide (nitric oxide synthase) and carbon monoxide (heme oxygenase), and the small molecule transmitters acetylcholine (choline acetyltransferase), glutamate (glutaminase) and GABA (glutamic acid decarboxylase). The presence and identity of the transcriptome-derived transcripts were confirmed using RT-PCR. The data presented here provide a foundation for future gene-based studies of neuromodulatory control at the level of neurotransmitter/modulator biosynthesis in Homarus.

De novo assembly of a transcriptome for the cricket Gryllus bimaculatus prothoracic ganglion: An invertebrate model for investigating adult central nervous system compensatory plasticity.

The auditory system of the cricket, Gryllus bimaculatus, demonstrates an unusual amount of anatomical plasticity in response to injury, even in adults. Unilateral removal of the ear causes deafferented auditory neurons in the prothoracic ganglion to sprout dendrites across the midline, a boundary they typically respect, and become synaptically connected to the auditory afferents of the contralateral ear. The molecular basis of this sprouting and novel synaptogenesis in the adult is not understood. We hypothesize that well-conserved developmental guidance cues may recapitulate their guidance functions in the adult in order to facilitate this compensatory growth. As a first step in testing this hypothesis, we have generated a de novo assembly of a prothoracic ganglion transcriptome derived from control and deafferented adult individuals. We have mined this transcriptome for orthologues of guidance molecules from four well-conserved signaling families: Slit, Netrin, Ephrin, and Semaphorin. Here we report that transcripts encoding putative orthologues of most of the candidate developmental ligands and receptors from these signaling families were present in the assembly, indicating expression in the adult G. bimaculatus prothoracic ganglion.

Molecular evidence for an intrinsic circadian pacemaker in the cardiac ganglion of the American lobster, Homarus americanus - Is diel cycling of heartbeat frequency controlled by a peripheral clock system?

Whether cardiac output in decapod crustaceans is under circadian control has long been debated, with mixed evidence for and against the hypothesis. Moreover, the locus of the clock system controlling cardiac activity, if it is under circadian control, is unknown. However, a report that the crayfish heart in organ culture maintains a circadian oscillation in heartbeat frequency suggests the presence of a peripheral pacemaker within the cardiac neuromuscular system itself. Because the decapod heart is neurogenic, with contractions controlled by the five motor and four premotor neurons that make up the cardiac ganglion (CG), a likely locus for a circadian clock is the CG itself. Here, a CG-specific transcriptome was generated for the lobster, Homarus americanus, and was used to assess the presence/absence of transcripts encoding putative clock-related proteins in the ganglion. Using known Homarus brain/eyestalk ganglia clock-related proteins as queries, BLAST searches of the CG transcriptome were conducted for the five proteins that form the core clock, i.e., clock, cryptochrome 2, cycle, period and timeless, as well as for a variety of clock-associated, clock input pathway and clock output pathway proteins. With the exception of pigment dispersing hormone receptor [PDHR], a putative clock output pathway protein, one or more transcripts encoding each of the proteins searched for were identified from the CG assembly; no PDHR-encoding transcripts were found. RT-PCR confirmed the expression of all core clock transcripts in multiple independent CG cDNAs; RNA-Seq data suggest that both the motor and premotor neurons could contribute to the cellular locus of a pacemaker. These data provide support for the possible existence of an intrinsic circadian clock in the H. americanus CG, and form a foundation for guiding future anatomical, molecular and physiological investigations of circadian signaling in the lobster cardiac neuromuscular system.

Circadian signaling in Homarus americanus: Region-specific de novo assembled transcriptomes show that both the brain and eyestalk ganglia possess the molecular components of a putative clock system.

Essentially all organisms exhibit recurring patterns of physiology/behavior that oscillate with a period of ~24-h and are synchronized to the solar day. Crustaceans are no exception, with robust circadian rhythms having been documented in many members of this arthropod subphylum. However, little is known about the molecular underpinnings of their circadian rhythmicity. Moreover, the location of the crustacean central clock has not been firmly established, although both the brain and eyestalk ganglia have been hypothesized as loci. The American lobster, Homarus americanus, is known to exhibit multiple circadian rhythms, and immunodetection data suggest that its central clock is located within the eyestalk ganglia rather than in the brain. Here, brain- and eyestalk ganglia-specific transcriptomes were generated and used to assess the presence/absence of transcripts encoding the commonly recognized protein components of arthropod circadian signaling systems in these two regions of the lobster central nervous system. Transcripts encoding putative homologs of the core clock proteins clock, cryptochrome 2, cycle, period and timeless were found in both the brain and eyestalk ganglia assemblies, as were transcripts encoding similar complements of putative clock-associated, clock input pathway and clock output pathway proteins. The presence and identity of transcripts encoding core clock proteins in both regions were confirmed using PCR. These findings suggest that both the brain and eyestalk ganglia possess all of the molecular components needed for the establishment of a circadian signaling system. Whether the brain and eyestalk clocks are independent of one another or represent a single timekeeping system remains to be determined. Interestingly, while most of the proteins deduced from the identified transcripts are shared by both the brain and eyestalk ganglia, assembly-specific isoforms were also identified, e.g., several period variants, suggesting the possibility of region-specific variation in clock function, especially if the brain and eyestalk clocks represent independent oscillators.
